DooR LATCH.

Application filed June 26, 1925." Serial No. 39,641.

' which the following is a specification;

The present invention relates to door latches; and its object is to provide such'a la-tcluvhich shall be very simple inconstruc- 'tion', comprising few parts whichmay be.

readily assembled; and further, to provide such a latch; having a latching bolt rockable in either direction into and out ofr'latchingv engagement with its -keeper; and further, to

provide such a latch havingimproved means for causing the latching bolt to automatically engage" its keeper when the door is These and any other objects hereinafter appearing are attained by,and the invention finds" preferable embodiment in, the door latch hereinafter particularly described in the body of thisspecification and illustrated by the accompanyingdrawings, in which Figure lis a face view of a door latch; I Figure 2 is a right-hand side view thereof; Figure 3' is a left-hand side view of the same; I Y

Figure 4 is alefthand side view thereof and of the latchs keeper;

Figure 5 is a front View of the latch and keeper, a portion of the casing being broken away; i

Figure 6 is a sectional viewof the latch and easing taken on line 66 of Figures 5 and 7; V,

Figure 7 is a sectional view of the same taken on line 7-7 of Figures 5 and 6; Figure 8 is a face view ofa modified construction of the keeper; and v Figure 9 is aside view thereof. In the embodiment of the; invention chosen for illustration by the drawings and,

has members 8, 9, spaced apart in the bolts transverse direction; which members rock and slide in bearings 10, ll'respectively in the right-hand wall of the casing, through which the ends 12,.13 of these-members eX- tend, whereby the bolt is held in position in the. casing. It will. be seen that when the handle portion 14 of thebolt is moved downwardly to disengage the end 7 from the keeper, the upper'member 8 rocksv on its bearing 10 while the lower member 9 slides -in its-bearing 11; and that, if the latchjis applied adjacent the right-hand free edge of a door, so that the ends of the casing are now reversed in position, they downward movement of said handle portion to disengage the bolt from the keeper causes the member 9 to rock on its bearing 11 while the member 8 sldies in-itskbearinglO. It will thus be s'een that'this latch may be appliedadjacent either the riglit-hand-edgeor the. left-hand edge of aswiging door. in Figures 8 and9,thekeeper 2 may receive Or, as indicated the outer end of the bolt either from above or from below; in which case, either member 8 or 9 may rock on its bearing and the other member slide in its bearing in the disengaging'movement 0f the bolt from the keeper.

The wall 16 of the casing has a bearing orifice 17 opposite the pair of spaced bearing orifices 1O, 11, the end 7 of the bolt projectlng through the orifice 17. A pair of vertically spaced apart supports or shoulders 18, '19 are formed in the bearing orifice 17, and

areadapted to receive the bolt in resting position thereon when the same isrocked in either, direction to keeper-disengaging position. -When the door is'shut, the bolt being held in such position, the end 7 ,of the bolt strikes-the keeper or thedoor jamb and is pushed "from the support or shoulder on which it rests and thereupon'falls into latching engagement with the keeper.

A wire spring 21 is seated-in the casing, its ends passing around the screws 20, 20 a'nd'its middle portion 22 extending from the front wall of the casing and pressing on the side of the bolt adjacent saidwall. 1 On either side of the main portion of the bolt the spring also presses at 23, 24 on the mem bers 8, 9. The action of this springtlius presses the bolt into its operative position in which its end 7 latchingly engages the kee er, and presses said click-57 into resting pos t-ion on the support 1 8-01 19; and also presses the members 8 9 in their rocking contact or engagement with their bearings 10, 11. This spring thus serves to hold the parts in place.

It will be seen that this latch is of very simple construction, comprising only three partsthe casing the latching bolt and the said spring; and that these parts may be readily assembled.

The invention being intended to be pointed out in the claims is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In a door latch: a keeper; a bolt having an operating handle portion and movable out of latching engagement therewith rockingly about either of a pair of axes spaced in the bolts transverse direction.

In a door latch: a. keeper; a bolt springpressed into latching engagement therewith and having an operating handle portion and movable out of said engagement rockingly about either oi a pair of axes spaced in the bolts transverse direction.

3. In a door latch: a keeper; a pair oi spaced bearings, a bolt having a pair of members spaced in the bolts transverse direction and movable rockingly and slidably in said bearings respectively in the bolts disengaging movements from the keeper.

4. In a door latch: a keeper; a pair of spaced bearings; a bolt spring-pressed into latching engagement with the keeper and having a pair of members s aced in the bolts transverse direction and movable rockinglv and slidably in said bearings respectively in the bolts disengaging movements from the keeper.

In a door latch: a keeper; a pair of spaced bearings; a. bolt having a pair of members spaced in the bolts transverse direction, one of said members being movable slidably and the other of said members being movable rockingly in said bearings respectively in the bolts disengaging movement from the keeper.

6. In a door latch: a keeper; a pair of spaced bearings; a bolt spring-pressed into latching ci'igagment with the keeper and having a. pair of members spaced in the bolts transverse direction, one of said members being movable slidably and the other of said members being movable roc-kingly in said he rings respectively in the bolts disengaging movement from the keeper.

7. in a door latch: a keeper; :1 pair of spaced bearings; a bolt having a pair of members spaced in the bolts transverse direction, one of said members being movable slidably and the other of said members being movable rockingly in said bearings respectively in the bolts disengaging movement from the keeper; a spring pressing the bolt into latching engagement with the keeper and pressing the second-mentioned of said members into engagement with the bearing on which it rocks.

8. In av door latch: a keeper; a casing having adjacent the keeper a bearing and having a pair of spaced bearings disposed oppositely to the first-mentioned bearing; a rockable bolt extending through the firstmentioned bearing and having a pair of members spaced in the bolts transverse direction and extending through said pair of bearings respectively, one of said members being movable slidably and the other of said members being movable rockingly in said pair of bearings respectively in the bolts disengaging movement from the keeper; a spring pressing the bolt into latching engagement with the keeper and pressing the secondqnentioned of said members into engagement with the bearing on which it rocks. 1 r

9. In a door latch: a keeper; a support; a pair of spaced bearings; a bolt having a pair of members spaced in the bolts transverse direction, one of said members being movable slidably and the other of said members being movable rockingly in said bearings respectively in the bolts disengaging movement from the keeper; a spring pressing the bolt into latching engagement with the keeper and into resting position on the support and pressing the second-mentioned of said members into engagement with the bearing on which it rocks.

10. In a door latch a keeper; a pair of supports; a pair of spacedbearings; a. bolt having a pair of members spaced in the bolts transverse direction and movable rockingly and slidably in said bearings respectively in the bolts disengaging movements from the keeper; a spring pressing the bolt into latching engagement with the keeper and into resting position on either of the supports and pressing said members into engagement with the bearings on whi'chthey respectively rock. i V

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 22nd day of June, 1925.
